Reddit's science section has banned climate change-denying trolls

One of the site's largest subreddits, r/science, has had enough of angry, conspiracy-spouting posters who do nothing but ruin legitimate debate.

Reddit’s science section - r/science - is one of the site’s default sections (or “subreddits” in the site’s parlance), and is one of the main places on the internet where experts and lay people can come together and chat about science. Its moderators, like the rest of those in charge of subreddits, have to juggle the site community’s strong belief in free speech with the need to prevent arguments, trolling, or anything else that could derail genuine scientific debate.

That’s why they’ve taken the step to ban “climate change deniers” from the subreddit. One of the moderators, chemist Nathan Allen, has written a blog post to explain why the decision was made (I’ve picked out the key paragraphs):

While evolution and vaccines do have their detractors, no topic consistently evokes such rude, uninformed, and outspoken opinions as climate change. Instead of the reasoned and civil conversations that arise in most threads, when it came to climate change the comment sections became a battleground.

...

After some time interacting with the regular denier posters, it became clear that they could not or would not improve their demeanor. These problematic users were not the common “internet trolls” looking to have a little fun upsetting people. Such users are practically the norm on reddit. These people were true believers, blind to the fact that their arguments were hopelessly flawed, the result of cherry-picked data and conspiratorial thinking.

...

We discovered that the disruptive faction that bombarded climate change posts was actually substantially smaller than it had seemed. Just a small handful of people ran all of the most offensive accounts. What looked like a substantial group of objective skeptics to the outside observer was actually just a few bitter and biased posters with more opinions then [sic] evidence.

Negating the ability of this misguided group to post to the forum quickly resulted in a change in the culture within the comments. Where once there were personal insults and bitter accusations, there is now discussion of the relevant aspects of the research.

I used to work as a barman in a pub with a semi-famous regular who obsessively tried to argue that renewable energy was a scam and nuclear power was a better option, and who would pick drunken arguments with other regulars about it just for the sake of it. It was very weird, and it made uncomfortable, so we barred them. This is a bit like that.

If you want to see an example of a good discussion about climate change, then head to the comments on r/science about this blog post. There’s a lot of discussion about whether this is a genuine pro-science move, whether it’s a suppression of genuine criticism, and what kinds of tone are acceptable when posting contrary opinions.

For example, there’s a small debate over the politicisation of the word “denier”, and how some who are sceptical of climate models feel they are equated with “holocaust deniers” for daring to speak out. It’s stupid, obviously, but the point is it’s a civil debate compared to what you might see elsewhere when it comes to climate change.

The final question that Allen poses, though, is an interesting one - why don’t newspapers ban people like this too? The scientific consensus that climate change is happening, and is driven by humans, is extremely comprehensive and compelling - but media outlets like the BBC tend to offer "balance" by giving fringe sceptics an equal platform.

r/science has roughly four million monthly unique visitors, which makes it roughly twice as popular a website as the New Statesman, and an influential scientific resource. Perhaps some editors could look to reddit's science moderators for inspiration.

The best Instagram accounts to follow if you love space

As new space findings hit the news on an almost daily basis, the app offers an alternative window onto the universe.

If there’s anything that can break us away from the humdrum monotony of modern life, it’s space. It renders us awe-struck and captures our imagination with its vastness and surreal imagery, and as astronomy-related research expands, cosmic mysteries continue to unfold.

Whether it’s the occurrence of rare celestial events, the discovery of exoplanets that could potentially harbour life, or the confirmation of gravitational waves that ripple through the space-time continuum, it seems that there are new findings propelled onto our newsfeeds daily.  

Yet one of the best ways of keeping up to date with the latest research and projects at the frontier of space is on Instagram, the social media platform. Here are some of the accounts you should be following to get the greatest insight into space:

1. SpaceX (@spacex)

The aerospace company SpaceX designs spacecrafts and reusable rockets in the hope that their technology can one day make human life multi-planetary. Spearheaded be CEO Elon Musk, the company has the lofty ambition of one day colonising Mars. Below is a spectacular image of the company’s Falcon 9 rocket in its first-stage entry:

2. International Space Station (@iss)

The International Space Station, a habitable satellite whirling around the Earth approximately 16 times per day in low orbit, has an Instagram feed displaying the equipment on board as well as stunning pictures of the Earth from a distance. Here’s a picture from the station 250 miles above earth depicting the Earth as an azure blue marble:

3. Tim Peake (@astro_timpeake)

Currently aboard the International Space Station is Tim Peake, a British astronaut. As he has carried out his work on Expedition 46/47 on the station, he has shared a range of photos of Earth that he has shot with his Nikon D4 from the vantage point of space, from reefs off the coast of Mozambique to the glint of sun highlighting Vancouver Island. Here we have a clear image of the Pacific “Ring of Fire”:

5. Nasa Goddard (@nasagoddard)

Nasa’s Goddard Space Flight Centre was the company’s very first flight centre. It’s the largest of its kind, and the official Instagram account for the centre serves as a highlight reel for everything NASA is working on. There are behind-the-scenes looks at the James Webb Space Telescope under construction, computer-simulated images of supermassive black holes, and clear views of distant galaxies captured by the Hubble Space Telescope:

 

Observations by the NASA/ESA Hubble Space Telescope have taken advantage of gravitational lensing to reveal the largest sample of the faintest and earliest known galaxies in the universe. Some of these galaxies formed just 600 million years after the big bang and are fainter than any other galaxy yet uncovered by Hubble. The team has determined for the first time with some confidence that these small galaxies were vital to creating the universe that we see today. An international team of astronomers, led by Hakim Atek of the Ecole Polytechnique Fédérale de Lausanne, Switzerland, has discovered over 250 tiny galaxies that existed only 600-900 million years after the big bang— one of the largest samples of dwarf galaxies yet to be discovered at these epochs. The light from these galaxies took over 12 billion years to reach the telescope, allowing the astronomers to look back in time when the universe was still very young. Although impressive, the number of galaxies found at this early epoch is not the team’s only remarkable breakthrough, as Johan Richard from the Observatoire de Lyon, France, points out. “The faintest galaxies detected in these Hubble observations are fainter than any other yet uncovered in the deepest Hubble observations.” By looking at the light coming from the galaxies the team discovered that the accumulated light emitted by these galaxies could have played a major role in one of the most mysterious periods of the universe’s early history — the epoch of reionization. Reionization started when the thick fog of hydrogen gas that cloaked the early universe began to clear. Ultraviolet light was now able to travel over larger distances without being blocked and thus the universe became transparent to ultraviolet light.

Roscosmos is the Russian Federal Space Agency at the heart of all space endeavours in Russia. The agency is involved in the maintenance and progression of the International Space Station, and is working on its own research projects such as a planned robotic mission to one of Mars’s moons.  Here’s the launch of a rocket from the Vostochny Cosmodrome which is under construction:

 

7. Nasa (@nasa)

Over the years, Nasa has firmly committed to pushing the boundaries of space exploration, and, as its 12.3m Instagram acolytes would agree, it has been successful. As part of the Frontier Fields campaign investigating galaxy clusters, a recent deep field image from the Hubble revealed bounds of galaxies in the constellation of Leo:

 

Nearly as deep as the Hubble Ultra Deep Field, which contains approximately 10,000 galaxies, this incredible image from the Hubble Space Telescope reveals thousands of colorful galaxies in the constellation of Leo (The Lion). This vibrant view of the early universe was captured as part of the Frontier Fields campaign, which aims to investigate galaxy clusters in more detail than ever before, and to explore some of the most distant galaxies in the universe. Galaxy clusters are massive. They can have a tremendous impact on their surroundings, with their immense gravity warping and amplifying the light from more distant objects. This phenomenon, known as gravitational lensing, can help astronomers to see galaxies that would otherwise be too faint, aiding our hunt for residents of the primordial universe.
